PRINTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 369,886, dated September 13, 1887. Application tiled May 16, 1887. Serial Nn. 238,3'2fl. (No model.)

To @ZZ whom t may concern:

Beit known that I, ALFRED SHEDLOOK, a citizen of the United States, residing at Jersey City, county of Hudson, State of New Jersey, have invented a certain new and Improved Printing Device, of which the following is a specification.

The object of this invention is to supply means for printing or impressing figures or characters on paper at equal distan ces throughout its length while it is being continuously fed forward.

My invention, when applied to a paper-bag machine, consists of a simple rotating printing devicearranged to impress the paper as it is fed to the folding apparatus, or while the paper is being formed into a tube, and actuated from any part of the machine working in unison with a device which determines the length of the bag or of the paper required to form a bag.

Paperbag machines in which the paper from a roll is primarily folded into a tubular form, or machines for making tubes and cutting them into lengths to be afterward oompleted as bags by other machines or by handlabor, are generally made adjustable, so that different sizes of bags or lengths of tubes may be made on one machine. To adapt my improved printing device to such a machine, a type-carrying arm is provided for each length of tube that can be made on the machine, the circumferences of the lcircles through which the types travel, or parts thereof, if more than one impression per revolution be made, being equal to the lengths of the tubes they are respectively designed to print. The shaft carrying these arms always rotates in unison with the device which determines the length of the bag, and is adjustable relatively to the table or former over which the paper travels, and the arms are adjustably connectedthereto, so that the impression may be made to occupy the proper positions on the bags or pieces severed from the tube. An ink-roller is provided, carried by an adjustable shaft and set in right position for the type to take ink therefrom between the impressions.

By reference to the accompanying drawings and the following description thereof the construction and operation of my improved printing device will be fully ascertained.

table b and former c by means of the feed-rollers d d', the disk e creasing the paper where it is to be folded and the paste-wheel j' applying paste to one of the edges. The shaft g, laterally arranged under the table b, is connected to the feed-roller d by the intermediate gear, 7L, which meshes into the gear-wheel on the shaft g and the gear-wheel j on the shaft of the roller d. A inciter-wheel, 7c, on the shaft g meshes into a similar wheel, k', on a shaft arranged longitudinallyto the table, which also carries the spur-wheel Z, drivingasimilar spur-wheel, Z', to the side of which is secured the knife Z2, which severs the lengths from the tube of paper, a. The dot-ted circles Z3 represent a pair of rollers which discharge the lengths of tube from the machine after they have been cut off by the knife Z2. By this arrangement it is evident that the shaft g always makes one full revolution for each complete action of the knife Z2, and that its speed in relation to that of the feed-rollers d d is governed by the relative sizes of the gear-wheels andj. To change this relation a different size of gear-wheel foreach length of paper to be cutis substituted for the wheel j, the intermediate wheel, h, being adjustable, as shown.

All the mechanism lso far described is old and gives a fair idea of the machine towhich my printing device is to be applied, whether it be taken as a complete tubing-machine or the tube-forming part of a paper-bag machine.

Through the table b, at any convenient distance from the feed-rollers d cZ, is formed the opening b, and at one side of this opening, under the table, is secured the pendent bracket m, having. a circular slot, m', formed through it concentric with the shaft g. In this slot the block n is clamped by means of the bolts n', and the shaft ois fitted to rotate in the bearing formed in the block a. On one IOO end of the shaft o is secured the chain-wheel p, which is driven from the chain-wheel q, secured to the shaft g by means of the chain q. On the other end of the shaft o,which extends some distance from the block n, is adjust-ably secured the collar r, provided with a nut, r', between which and the flange r2 of the collar is clamped the arm s, carrying the type s.

Fitted to slide in the curved slot m', below the block n, is another block, t, from which projects the rod t', said block being clamped in any required position on the bracket m by the nut t2. The ink-roller u, which may bemade of Wood or other suitable material and covered with felt, is fitted to rotate freely on the rod t', and is held in any desired position thereon by means of the box c, which has two lugs perforated to fit upon the rod t', one of which has a set-screw, t', passing through it for securely fasteningthe box to the rod t. rIhe ink-roller tu, it will be observed, is free to rotate on the rod t between the lugs of the box v, this box acting simply asa frame to hold the roller u upon the rod. The box t may be used to retain a supply of ink for the roller; but under ordinary circumstances this is not necessary, as the feltcovering of the roller will generally hold sufficient ink for all practical purposes.

At Figs. et and 5 is shown a detached typecarrying arm, s, smaller than the one shown -attached in operative position in the other views, and designed to print a shorter length of -paper or tubes' formed on the machine. Double arms s are shown diametrically arranged and each provided with a type s, and the chain-wheel p is twice the size of the chainwheel g, so that one of the types comes in contact with the paper, as the paper is'drawn forward by the rollers d d, at equal speed therewith, for each revolution of the shaftg-and each action of the knife on the paper. This arrangement may be variedwithout departing from the spirit of my inventionas, for instance, three equidistant type-arms may be sizes of tubes.

To adj ust this printing device, the collar i' is so set upon the shaft 0 that the type s will impress the paper or tube centrally. The block fn, is set and clamped rigidly in the slot w of the bracket in such position that the type s will just touch the under side of thepaper, a. The ink-roller a is then set on its shaft t so as to be in the plane of motion of the type, and the shaft is vertically adjusted by shifting the block t in the slot w' to bring the surface of the felt covering of the ink-roller into position to be touched by the type. rlhe arm s is then set on the collar r so as to impress the parts of the paper that are near the cuts made bythe knife, or any desired parts relatively thereto.

It will be understood that any positivelyrod or shaftarranged parallel to the type-arm shaft and adjustable to and from the sarne,sub stantially as set forth.

2. The combination, with a machine for tubing paper, of a printing device consisting of a rotating type-arm carried by and adjustably connected to a shaft running in a bearing adapted to be moved to and from the paper, an ink-roller adj ustably held in position relatively to the type-arms, and a positive-acting gearing connecting the type-carrying shaft to a shaft of the tubing-machine, which governs or works in unison with adevice determining the lengths of tube made, substantially as set forth.

3. In a p rinting device forimpressing paper as it is fed from a roll, in combination, ashaft of the machine working in unison with the feeding device, a frame or bracket provided with a curved slot formed concentric with the shaft, a sliding block held in the curved slot, a shaft carried by the sliding block, type-arms adj ustably connected to this shaft,positive-act ing means connecting this type-arm shaft to the shaft of the paper-feeding machine, and an inking device for applying ink to the type, substantially as set forth.

4. In a printing device, in combination, a shaft fitted to rotate in an adjustable bearing, a collar provided with a iiange and nut and clamped upon the shaft, and a type-arm held between the liange and nut of the collar, substantially as set forth.

5. In a printing'device for impressing paper as it is fed from a roll, in combination, ashaft of the machine working in unison with the feeding device, a frame or bracket provided with a curved slot formed concentric with the shaft, a sliding block held in the curved slot, a shaft carried by thesliding block, type-arms adj ustably connected to this shaft, positiveacting means connecting this type-arm shaft to the shaft of the paper-feeding machine, an ink-roller fitted to rotate on a rod arranged parallel to the type-arm shaft and adjustable in relation thereto, and a box or frame having lugs iitted on the rod, between which the inkroller is held on any desired part of the rod,
